Founded in 1945 by Henry Bleck and his son John, Bleck Engineering has been a family-run firm for over 80 years, known for personalized service, technical excellence, and integrity.
Long before the firm was officially established, Henry Bleck was already distinguishing himself in the field. His journey began at Marquette University, where he was an active member of the Sigma Phi engineering fraternity in 1921. These early years laid the academic and professional groundwork for what would eventually become a multi-generational legacy.
Henry Bleck and his son John (Jack) founded Bleck Engineering in Waukegan. This photograph captures the two founders together—the beginning of a company built on integrity, precision, and family values.
Their partnership established the core principles that still guide us: more than a business, a commitment to the community and to excellence in every project.

What began with Henry and Jack grew into a family enterprise. Jack's four sons— William (Bill), Jack R., Michael, and Patrick—all carried the torch forward.
Today that legacy continues with the next generation, led by Matthew G. Bleck. The spirit of Bleck Engineering remains the same: honoring our history while building for the future.
